The objective of this study was to investigate whether melamine (MEL) is biotransformed into cyanuric acid (CYA) in male broiler chickens. The effects of the dietary addition of MEL and CYA alone and in combination on the growth performance and mortality of the chickens were also investigated. The chickens were divided into six experimental groups and were fed diets with an addition of 50 or 100 mg/kg MEL or 50 or 100 mg/kg CYA of diet, with the contaminants added separately or in combination. The control group was fed a diet without MEL or CYA. At the end of the experiment (day 40), samples of liver, kidney and breast and thigh muscles were collected from 12 birds per treatment group and were analysed for the presence of MEL and CYA. This study showed that MEL is biotransformed into CYA in broilers. Higher concentrations of MEL or CYA in the diet increased the presence of their residues in tissues, and the CYA residue concentration was several times higher in the respective tissues than the MEL residue concentration. The dietary addition of MEL and CYA did not affect the mortality rate, feed conversion ratio or body weight of the chickens.

This study was conducted to evaluate the nutritional value of potato tuber meal (PTM) for broiler chickens during growing (22–42 days) and finishing (43–49 days) periods. A total of 360 1-day-old male broiler chicks (Ross 308) were fed a corn-soybean meal-based diet until 21 days of age, then randomly assigned to six experimental diets, in which corn was replaced by PTM at 0%, 10%, 20%, 30%, 40%, and 50% levels by weight, respectively. Replacement of corn with 10%, 20%, 30% and 40% PTM had no effect on feed intake, bodyweight gain, and feed conversion ratio (P > 0.05). However, replacing 50% of corn with PTM resulted in a significant reduction (P < 0.05) in bodyweight gains from 22 to 42, and 22 to 49 days of age. Moreover, there was a significant (P < 0.05) increase in feed conversion ratio when 50% of corn was replaced by PTM. Corn replacement with PTM did not affect (P > 0.05) carcass and organ weights of broilers at 42 days of age. However, compared with the Control group, the relative length of the ileum was increased (P < 0.05) by inclusion of PTM in the diets, and it was statistically different for broiler fed diets in which 20% or 50% of corn was replaced by PTM. The serum concentrations of triglycerides, cholesterol, urea, and uric acid were not affected (P > 0.05) by diet inclusion of PTM. Replacing 50% of dietary corn with PTM significantly (P < 0.05) decreased apparent ileal digestibility of protein at 42 days of age. The excreta content of uric acid was not affected by diet inclusion of PTM. In conclusion, our results showed that PTM can replace dietary corn up to 40% during the growing and finishing periods with no adverse effects on growth performance of broiler chickens. Also, replacing up to 40% of corn with PTM in broiler diet had no adverse effect on carcass composition, blood constituents, and apparent ileal digestibility of protein at 42 days of age.

Xylan oligosaccharides (XOS) can promote proliferation of Pediococcus acidilactic BCC-1, which benefits gut health and growth performance of broilers. The study aimed to investigate the effect of Pediococcus acidilactic BCC-1 (referred to BBC) and XOS on the gut metabolome and microbiota of broilers. The feed conversion ratio of BBC group, XOS group and combined XOS and BBC groups was lower than the control group (P &lt; 0.05). Combined XOS and BBC supplementation (MIX group) elevated butyrate content of the cecum (P &lt; 0.05) and improved ileum morphology by enhancing the ratio of the villus to crypt depth (P &lt; 0.05). The 16S rDNA results indicated that both XOS and BBC induced high abundance of butyric acid bacteria. XOS treatment elevated Clostridium XIVa and the BBC group enriched Anaerotruncus and Faecalibacterium. In contrast, MIX group induced higher relative abundance of Clostridiaceae XIVa, Clostridiaceae XIVb and Lachnospiraceae. Besides, MIX group showed lower abundance of pathogenic bacteria such as Campylobacter. Metabolome analysis showed that all the 3 treatment groups (XOS, BBC and MIX) showed lower concentrations of sorbitol and both XOS and BBC group had higher concentrations of pyridoxine levels than CT group. Besides, XOS and BBC groups enhanced the content of hydroxyphenyl derivatives 4-hydroxyphenylpyruvate 1 and 3-(3-hydroxyphenyl) propionic acid, respectively (P &lt; 0.05). Notably, MIX group enhanced both 4-hydroxyphenylpyruvate 1 and 3-(3-hydroxyphenyl) propionic acid (P &lt; 0.05). Thus, XOS and BBC may have a synergistic role to improve the performance of broilers by modulating gut microbiota and metabolome.

Senna Obtusifolia

The eight-week feeding trial was conducted to evaluate the nutrient digestibility and growth performance of broiler chickens fed raw or processed Senna obtusifolia seed meal (SOSM). Six experimental diets were compounded to contain 0% SOSM and 20% each of the raw, boiled, soaked, sprouted and fermented SOSM respectively. Two hundred and sixteen (216) broiler chicks were randomly allotted to six (6) dietary treatments in a randomised complete block design with three (3) replicates containing 12 chicks each. Data were collected on nutrient digestibility, feed intake, weight gain, feed conversion ratio and mortality. The result of productive performance indicated that feed intake, weight gain and feed conversion ratio were significantly (P<0.05) depressed in broiler chickens fed raw, soaked and sprouted Senna obtusifolia seed meal. However, broiler chickens fed fermented SOSM showed better (P<0.05) productive performance that was close to those fed the positive control diet (0% SOSM). The mortality rate did not reveal any particular trend. However, the low mortality rate recorded in the different treatments indicated broiler chicken can tolerate up to 20% of either raw or processed SOSM. Broiler chickens fed raw SOSM recorded lower values for dry matter (63.06%), crude protein (52.46%), ether extract (53.88%), crude fibre (30.72%) and nitrogen-free extract (46.11%) digestibility than those fed the other processed SOSM. The nutrient digestibility of broiler chickens fed fermented SOSM was significantly (P<0.05) better followed by those fed boiled Senna obtusifolia seed meal. For instance, broiler chickens fed fermented Senna obtusifolia seed meal recorded the highest crude protein and ether extract of 69.91 and 70.03% compared to the other processing methods. It can be concluded that 20% fermented SOSM can be incorporated in the diets of broiler chickens with acceptable depreciation in biological performance. Slightly lower levels of boiled SOSM can be included in the diet of broiler chickens but the levels should be ascertained in further studies.

The aim of this study was to evaluated the effect of soaked Mucuna pruriens (MP) seeds in tap water, acid or alkaline solution + cooking on its L-Dopa content and on the productive performance of broiler chickens. Ninety-six sexed chicks aged 21-days old with an initial live weight of 720 ± 80 g were used. Four diets were used, a control without MP (C) and three diets including 25 % MP: a) soaked MP in tap water + cooking (WMP); b) soaked MP in acetic acid solution + cooking (AAMP); c) soaked MP in calcium hydroxide solution + cooking (CHMP). The alkaline treatment reduced 71 % of L-Dopa in comparison to acid or water treatment (53 % and 41 % respectively). In the starter phase, the acid group had the lowest live weight gain (p<0.05) and highest feed conversion ratio when compared to control (p<0.05). Productive performance of birds fed with CHMP and C group was similar (p>0.05). In the finisher phase, there was not statistical difference in feed intake, live weight gain and feed conversion ratio among treatments (p>0.05). No differences were observed in carcass yield (p>0.05), but, the birds fed MP or AAMP had a heavier liver than birds on C group (p<0.05). Results shown that 25 % of CHMP can be used as feedstuff for broiler chickens without negative effects in their productive performance. Keywords: Velvet bean, L-Dopa, Poultry, weight gain.

The present study was conducted to investigate the effects of using probiotic <em>Yeasture</em>® at different rearing periods on performance, intestinal microbial population and carcass traits in broiler chickens. A total of 378 one day old chickens (male and female) were randomly allotted to one of the 21 floor pens in a completely randomized design with seven treatments and three replicate groups and eighteen chickens in each group (9 male and 9 female). The Experiment treatments consisted of seven groups: A (control, without probiotic), B (prebiotics feeding between 1 to 10 days), C (prebiotics feeding between 1 to 24 days), D (prebiotics feeding between 1 to 42 days), E (prebiotics feeding between 11 to 24 days), F (prebiotics feeding between 11 to 42 days) and G (prebiotics feeding between 24 to 42 days). The chickens received the desired probiotic at different days of rearing period. The basal diets were corn and soybean meal, so 0.3 g/kg of basal diets in starter (1-10 days), 0.25 g/kg of basal diets in grower (11-24 d) and 0.2 g/kg of basal diets in finisher (24-42 d) period of probiotic was added to the basal diets for each other than treatment. The growth performance (evaluated through body weight gain, feed intake and feed conversion ratio), intestinal microbial population (the measurement of <em>Lactobacillus</em> and <em>Coliforms</em>) and carcass traits (relative weights of carcass, intestine, liver, gizzard and abdominal fat) were determined. Body weight gains and feed conversion ratio were significantly improved in broilers with added probiotic compared to the control group (P&lt;0.05) whereas feed intake was not significantly altered. In addition, intestinal microbial population and carcass and gizzard weights markedly increased in the probiotic treated birds compared to control chickens (P&lt;0.05). These results show that diet supplementation with probiotic <em>Yeasture</em>® at the early days of the rearing periods of broiler chickens especially, 1 to 24 and 1 to 42 days, had a positive effect on intestinal microbial population, leading to more nutrients being assimilated by the chickens and consequently greater performance in broiler chickens.

This study was conducted with Thai broiler chicken (KKU 1) to investigate the effect of citric acid by-products from rice (CABR) on growth performance and villi histology. A total of 192 broiler chicks were subject to three dietary treatments, including 0% CABR, 3% and 6% of dry matter. Body weight gains, feed intake, feed conversion ratio, survival rate, and production index (body weight gain, feed intake, feed conversion ratio, survival rates, and productive index, respectively) were considered for growth performance evaluation. Villi height (µm), crypt depth (µm), and villi: crypt ratio were recorded for the villi histological measurement. The performance did not show a significant effect when compared with the control group during at ages ranging from 1 to 56 days. Villi histology indicate a significant effect on villi height (µm), crypt depth (µm), and villi: crypt of broiler chicks compared with the control group. Also, the use of 3% CABR caused a reduction microbial contamination in chicken fecal matter. In conclusion, supplementation of CABR had no negative effects on growth performance of Thai broiler chicken (KKU 1). Also, the addition of 3% CABR to the feed might help reduce fecal microbial contamination and affect the villi histology of Thai broiler chickens (KKU 1).

Effect Of Feeding

This study determined the effect of feeding trough shapes on the growth performance, carcass characteristics and cost benefit analysis of 180 broiler chickens of two strains (90 birds each of Marshal and Hubbard strains) subjected to circular, rectangular and square-shaped 2 feeding troughs with a surface area of 900 cm each. The broiler chicks were brooded for two weeks and thereafter allotted into six treatment groups of 30 chicks each, consisting of 3 replicates of 10 chicks per replicate. Daily weight gains were recorded and at the 8th week, 3 broiler chickens that were of average weights for each replicate were used for carcass evaluation. Data were analysed using PRO GLM at 5% level of significance. Results showed that feeding trough shapes significantly (P< 0.05) influenced the final weight, feed intake and feed conversion ratio. Birds on circular feeding trough recorded the best feed conversion ratio (2.98±0.03). The feeding trough shape and strain did not significantly (P>0.05) affect the cut-up parts and organs measured. In the interaction between strain and feeding trough, the dressing percentage was significantly (P<0.05) affected, but did not follow any trend. Marshal strain on square feeding trough recorded significantly (P<0.05) lowest production cost (N539.25) while Hubbard strain on circular feeder had the highest cost of N605.46. It was concluded that, in terms of cost of production, the square and rectangular shaped feeding troughs could be adopted.

Zinc Bacitracin

Two experiments were conducted to assess the effect of delayed access to feed after hatch and the potential of two carbohydrate oligomers, trehalose and palatinose, as supplements for early feeding of broiler chickens. A total of 360 and 252 straight run broiler chicks were used in Experiments 1 and 2, respectively, with each involving six treatments and six replicates. The diets were commercial in nature and supplemented with palatinose or trehalose (at 10 or 20 g/kg). Chicks were allowed to access feed within 8 h of hatch or 36 h. In Experiment 2, the supplements were fed at 10 or 20 g/kg diet; the commercial diets was also fed immediately or delayed. One of the diets contains zinc-bacitracin at 50 ppm and fed within 8 h of hatch. Delayed access to feed and water was found to reduce starting weight at placement whereas early access to feed generally improved it. Supplementation with trehalose, in particular led to higher (P < 0.001) 21-day weights than in the other groups although feed conversion ratio was not improved. The benefits of early feeding was demonstrated and trehalose may have some potential as an early feed supplement but further studies are required into how it can be applied at economic levels to minimise production costs down.
